45Nrth

Before getting these, I used the 2 inches Marathon ice, and liked them. However, with any snow beyond 2 inches, I tended to bog down. In comparison, the 45nrth are far more surefooted in deeper snow and ice. The price is more rolling resistance on dry roads. It is a compromise I'm willing to make as bike is my main mode of transportation

If you live in a city that gets freezing rain, or frozen roads, but not much snow, the Marathon ice is a better tire. These are more than what you need. If you have to ride in loose snow and ice, these are the best, unless you are going way fatter

I inserted these studs on a Dillinger 4.6 inch width tire that is on the back wheel. I have been riding almost exclusively on a groomed snow trail. The trail has sections of several hundred feet of pure ice at times. The traction on ice is great, I can't break the rear tire loose while seated and pedaling hard. I able to go up icy inclines and over cambered icy sections of the trail without any loss of traction. Corners on the ice are not a problem. I installed the studs on the Dillinger which is on the back wheel. I also bought a wrathchild pre-studded tire that is on the front wheel. The studs are light, and have held up well. I haven't lost any out of either tire. It wound be nice if they were a bit longer for traction on a skiff of snow over ice. They are expensive but much safer on ice than not having studs.

Use these with SPD's on my gravel bike. Was a real step up from my regular cycling shoes with toe covers in cooler weather.

For me I-chose size 44. One size over my normal. Particularly important if you are going to use heavy socks.

Did a 40 miler over three hours in 35-45 degree temps. My feet stayed comfortable. I'm happy with my purchase. Not sure how they would perform in temps below freezing. Quality seems to be there and time will tell regarding durability.

I commute to work every day and you never know what the road conditions will be like in winter. Because of climate change I note that I am facing ice more and more frequently. Studded tires are an absolute must. I already had a decent studded tire on the front but my rear tire studs were worn down too much. This tire is the perfect match for me! There are lots of studs so even on icy patches I can still get a grip and accelerate if needed. The tire also works well on bare patches - the studs don't slow me down as much as prior models did. And the main thing is that I feel secure with this tire. In retrospect I should have bought 2 of these - for the front and the back. You can bet that I'll be doing so in the very near future! I strongly recommend this tire to fellow winter bikers.
